Title: Butene-1 polymerisation and copolymers obtained thereby
Inventor: CLARK KEITH JASPER
IPC: C08F210/00
Filed: 1963-10-14
Abstract: A solid crystalline copolymer of butene-1 with a minor proportion by weight of 4,4-dimethylpentene-1 which crystallises from the melt in a form substantially stable to mechanical shock, is obtained by treating butene-1 and 4,4-dimethylpentene-1 with a stereospecific polymerisation catalyst.  The preferred catalyst is a trivalent titanium catalyst activated by an aluminium alkyl compound, and may be pretreated with propylene or 4-methyl-pentene-1. 4,4-dimethylpentene-1 is preferably used as diluent which may be recycled.

Filed: 1973-08-28
Abstract: 1409590 Vehicle wheel assemblies KARL SCHAEFF KG MASCHINENFABRIK 28 Aug 1973 40430/73 Addition to 1337062 Heading B7D [Also in Division E1] The double axle ground wheel assemblage of the shovel excavator of Specification 1,337,062 is replaced by a modified adjustable ground wheel assembly that permits of variation of the wheel base of the excavator from a short wheel base for towing to a long, stable wheel base for use when operating at a work site. In the shown embodiment each wheel 21, 22 is mounted on an associated swing link. The links are pivotally mounted on the chassis at the extremities thereof so that they can be swung, when the associated chassis extremity is raised, through at least 180 degrees. The swinging of the links may be caused by gravity and upward pressure of the ground as the chassis extremity is raised and lowered by suitable operation of the excavator with the shovel thereof bearing on the ground. Alternately the movement can be caused by piston cylinder units acting between the links and the chassis. The links, which normally abut directly or through resilient buffers the underside of the chassis, can be locked in various angular positions relative to the chassis to allow of the excavator working on slopes. The links of each pair of laterally aligned wheels may be firmly connected together. In an an alternative construction at least one pair of wheels can be arranged on profiled frame parts which are supported in longitudinally extending guides on the chassis, the parts being lockable to the chassis at a number of positions along the guides.

Title: Improvements relating to aircraft wings
IPC: B64C3/54
Filed: 1961-11-14
Abstract: 919,793. Aircraft control surfaces. CACIAGLI, S. Nov. 14, 1961, No. 40715/61. Class 4. An aircraft wing has two sets of surfaces each pivoted about a span-wise axis lying downstream of the leading edge, the surfaces of one set being movable relatively to each other and extending forwardly to the leading edge, the surfaces of the other set being movable relatively to each other and extending towards the trailing edge, and means for pivoting the surfaces between retracted and extended positions relative to the wing. Fig. 8 is a cross-section through the surfaces in extended position, showing the wing in broken line. The upper surface 36 of one set and the lower surface of 42 of the other are integral, as are the surfaces 38, 40. In the retracted position, these surfaces and a fixed part 32 constitute the normal wing profile. The one set of surfaces 36, 38 and the other set 40, 42 may pivot about different axes, being interconnected by gearing so that the two sets pivot together, possibly through different angles. When. extended, the surfaces increase drag and reduce lift, to provide yawing and rolling moments if operated in one wing only, or acting as airbrakes if operated in both wings. The surfaces may be perforated to increase their drag. A plurality of such sets of surfaces may be disposed side by side in a wing, the angular movement of the surfaces for a given control command by a human or automatic pilot increasing going spanwise. The surfaces in the two wings may be operated by independent pedals subject to one-way acting centering springs. The pivots for the surfaces may be extensions of the wing spars.

Abstract: 1,118,709. Valves. COMMERCIAL SHEARING & STAMPING CO. 30 Sept., 1965 [26 April, 1965], No. 41622/65. Heading F2V. In a two-spool valve, when either of the spools is moved from the neutral position, flow from an inlet 21, 22 to an exhaust passage 24 via bifurcated passage 23 is prevented. When the lower spool 19 is moved to the left, fluid flows from the inlet and via bores 25, 26 in the spool and check valve 27 to a work chamber 13 and thence to one side of a double-acting power device, fluid from the other side of the device flowing to an exhaust passage 18 via chamber 14 and groove 28. When this spool is moved to the right, chamber 14 is pressurized and chamber 13 is exhausted via groove 29 and passage 17. When the upper spool 20 is moved to the left, fluid flows from passage 23 and via bores 32, 35 in the spool to a work chamber 15 connected to one side of another double-acting power device, the other side of this device being exhausted via chamber 16, groove 36 and passage 18. When spool 20 is moved to the right, chamber 16 is pressurized via passage 22, check valve 31, chamber 30 and bores 32, 35, and chamber 15 is exhausted via groove 37 and passage 17. Thus, when spool 19 is actuated, movement of spool 20 to the left has no effect since spool 19 obturates passage 23. Full leftward movement of spool 20 interconnects work chambers 15 and 16 via groove 36.

[Also in Division G4] An automatic, coin-freed machine, in which corn (maize) is popped and cooked in hot oil, comprises a stationary popping chamber C surmounted by a hopper 5 and a container RC, in which raw, unpopped corn is stored. A sliding gate 9 is opened and closed to allow a measured batch of corn to pass, from the hopper, into a chamber 8 and a pivoted gate 6 is then opened to allow the batch of corn to fall into the popping chamber and on to the perforated portion of a swingable gate G closing a discharge opening in the lower end of the chamber. A measured amount of oil is dispensed, from a pump O, into an oil pan 10, heated by electric cartridge heaters 36, and the pan is swung, on pivoted arms 12, from the position shown in Fig. 1 into the popping position shown in Figs 2 and 7, in which the batch of corn, the perforated portion of the closed gate G and the lower end of the popping chamber are submerged in the heated oil. After being held for a predetermined time in this position, the pan is swung back to the position shown in Fig. 1 and the gate G is swung open to allow the popped corn to fall, by gravity, from the machine. The machine also comprises an operating gear 16, which is rotated, intermittently on a shaft 23 once during each popping cycle, by the spur gear 17 of an electric motor M, controlled by a start-stop micro-switch MS and an automatic timer (not shown). A roller 16a is pivoted on the side of the gear 16 and contacts cam mechanisms 20 and 6a and a cam 18 to open the gates 9, 6 and G. The cam mechanism 6a also actuates the microswitch. The arms 12 are secured to shafts 24 and 26 rotatably mounted in the main frame of the machine. A link 38 is pivoted, at 39, to the gear 16 and, at 38b, to a link 38a secured to the shaft 24, to swing the pan between the aforesaid positions. A cam 40 operating the pump O is secured to the shaft 26. The cam 18 is secured to the shaft 24 and a link 34, attached to a pin 33 on the gate G, is pivoted to the cam 18 to ensure that the gate G is closed, when the pan is moved into the popping position, and is opened, when the pan is swung away from this position. Tensioned springs S1 S2 and S3 urge the gates 6, 9 and G towards their closed positions. The coin-operating mechanism is not described or illustrated.
